Patentedl Sept. 8, 1931 UNITED STATES HENRY D. ROACH, 0F MINNEAPOLIS, IMIINNESO'ILA` AUTOMATIC SASH `OPERATOR Application filed January 17, 1930. Serial No. 421,429.

This invention relates to automatic sash operators.

It is an object of this invention to provide a novel and improved storm sash operator of cheap and simple construction which will automatically open and close a swinging storm sash applied to a window frame as a sliding window sash mounted in the frame is raised and lowered.

It is another object of the present invenA tion to provide suoli an operator for the storm sash which has no positive connection with the window sash and will permit the window sash to be raised to its full height.

To. these ends, the invention consists in the novel parts and novel combinations of parts, hereinafter defined in the claims and described in the following specification, made in connection with the accompanying drawings, wherein like reference characters refer to the same or similar parts throughout the various views and, in which,

' Fig. 1 is a vertical section through a window frame having mounted therein ay sliding window sash and a swinging storm sash, the same frame being equipped with an embodiment of the present invention andthe parts being shown in one position in full lines and in another position in dotted lines; and

Fig. 2 is a horizontal section taken line 2-2 of Fig; 1.k f

Referring to the drawingsl portions of a window frame of standard constructiony are illustrated, whichinclude the jamb 3, sill 4, window board 5, inner abutment strip 6 for the lower window sash, spacing strip7 between the lower window sash and the upper window sash and spacing strip 8 between the upper window sash and the storm sash. The lower window sash mounted for verti cal sliding movement is designated by the numeral 9 and carries the pane of glass 10 The storm sash is designated by the numeral 11 and carries the pane of glass 12.` The on the storm sash 11 is pivotedat its upper end (not illustrated) for swinging movement of the lower end of the sash outwardly from the window frame. i.

1n accordance with the present invention,

merely a screw secured tothe outer spacing strip 8. The bell' crank lever 13 has an arm 13a which normally projects upwardly from the pivot 14 when, the two sashes 9 rand 11 are closed and may, accordinglybe called the upper arm, of thelever. The bell crank lever 13 also has an arm 13b which normally projects downwardly and inwardly from the pivot 14 when the sashes 9 and 11 are closed and, accordingly, may be designated the lower arm of the lever. Pivotally secured to the end of the upper arm 130iy isa U-shaped slider 15 through which a rod 16, fixed to the. lower portion of one side of the storm sash 11, extends. The rod 16 forms a track to permit sliding movement of slider 15 upwardly and downwardly thereon and Y for this reason the rod 16is preferably in.-

wardly .spaced` at its medial portion from the storm sash 11, the two ends of the rod being preferablyy bent as shown and flattened in order ythat they may be readily secured to the storm sash. The lower end-of theV rod 16 will act as a stop tolimit the downward movement of the slider .15 and,A accordingly,-,the upward r`movement of they arm 13?) of the lever. K Thek end of the lower arm 13b is screwthreaded and has securedV thereto a screwthreaded socket 17 lprovided at its lower end with a` forked portion through which ya pivot 18 extends carrying a roller 19. At diametrically opposite points on'the inner end of the socket 17, apertured ears 17a, are formed and a coiled tension spring 2O is hooked at one end through the aperture in one of the ears 17a, and is secured at its other end to an eye 21 mounted on the jamb 3 between the strips 7 and 8 well above the pivot 14. f In installing one` ofthe operators on a window frame, before the spring 20 isat- V5' tached to the socket V17, the socket willbe screwed inwardly or outwardly on the screwthreaded portion Vof ,the arm 13b of the bell crank lever, until when the lowerfwindow sash 9fand-the storm sash 11 are both closed, f-

the roller 19 will strike and tightly abut the outer side of the lower portion oi the window sash 9. The spring 2O may be then hooked through the aperture in one of the ears 17a, two ears preferably being provided so that quite line adjustment of the spacing ot the roller 19 'from the pivot 14 may be provided. The spring 2O when attached, will then hold the socket 17 from turning relative to the lower arm 13b and will maintain the pivot 18 tor the roller 19 in horizontal position.

Considering that the two sashes 9 and 11 are in the closed position illustrated in Fig. 1, the parts ot the sash operator will assume the position indicated in full lines Fig. 1, the spring 20 exerting tension on the arm 13?) to urge the same upwardly. When the window sash 9 is raised, the window sash will be moved relative to the bell crank lever until the outer edge of the window sash is Acarried upwardly past the roller 19, the roller acting to permit thismovement without undue friction.` Then the lower edge ofthe window sash is raised above the lower position oit the roller as shown in full lines Fig. 1, the spring 2() will canse the arm 13b of the bell crank lever to be carried npwardly with the window sash below the saine until the lower arm 13?) has arrived at the position indicated in dotted lines Fig. 1 withthe roller 19 projectii'ig directly into the path of downward movement of the window sash 9. During this moif'ement of the lower arm 13b, the upper arm 13a will be swung downwaivllj,7 and outwardly causing the slider 15 to move downwardly on the rod 16 to swing the lower portion of the storm sash 11 outwardly to the dotted position and thereby opening the storm sash. As has been stated, the lower portion of the rod- 1G will limit the downward sliding movement ot' the slider 15 on the rod and this limiting action will occur to prevent 'further movement of the bell crank lever 13, while the roller 19 in its upward movement still projects in thel path ot downward movementlof the window sash 9. The window sash can, oit course, be raised to its lull height without all'ecting the operator after the window sash has been first raised to a point immediately above the dotted position of the roller 19 shown in Fig. 1. The distance that the storm sash 11 will be swung open will, of course, depend on the extent that the window sash 9 is raised until the window sash is raised to such a point that it extends above the dotted position of the roller 19 in the drawings, whereupon the storm sash will be swung open to its fullest possible extent. The draft of fresh air into the room may thus be varied at will depending on the height to which the window sash 9 is raised.-

When the window sash 9 is lowered, after having been raised, the lower edge ot the sash will lirst strike the roller 19 and swing the lower arm 13b of the bell crank lever downwardly with the sash until the lower and outer edge of the sash carried past the roller. In this position, the parts of the operator and storm sash 11 will have been swung to the position shown in full lines Fig. 1, with the storm sash completely closed and abutting the strip S. As the window sash 9 is lowered beyond this point, the lower edge ol" the sash will be carried downwardly beyond the roller 19 and the roller will, accordingly, run upwardly a short dirlar tance on the outer side of the lower portion 36 of the window sash, so that the storm sash/ will be securely locked in closed position. In this position it will be impossible to open the storm sash from the outside ot' the house or other structure within which the window S frame is situated and it will bc unnecessary to lock the upper and lower sashes of the window together. As the storm sash will be tightly held in closed position, there will. be no danger that the saine will rattle or will be caught by the wind and blown oil the window frame.

In practice, two of the operators will pret erably be provided for each window frame, one operator being situated at each side et the frame. The operator can be readily removed with the storm sash from the window frame by merely unscrewing the screw 14 :torming the pivot for the bell crank lever 13 and unhoolring one end oit the spring Q0. The operator can be similarly very easily installed when the storm sash is placed on the window frame for winter use. As the operators have no positive connection with the lower window sash 9, the window sash is capable oi its full natural sliding movement and the operators will not prevent raising movement of the sash 9 for cleaning ol the pane 10 or the like.

The parts ofthe presentV device are few, and the construction and operation o'l the same are simple. The device has been successfully demonstrated in actual practice.

It will, of course, be understood that variVM ous changes may be made in the vform, details, arrangement and proportions of the various parts without departing from the scope of the present invention.
